Israeli jets struck a series of Iranian military targets in Syria early on Monday, the military said in a rare departure from its years-long policy of ambiguity regarding activities in neighboring war-torn Syria.

The military said the targets included munition storage facilities, an intelligence site and a military training camp.

That followed a rare Israeli daylight air raid near the Damascus International Airport.
